The MPS-488HP power supply delivers DC power and bal-
anced audio to Meyer Sound loudspeakers that require a 
48 V DC external power supply. The MPS-488HP is a multi-
channel, switched-mode, regulated power supply that occu-
pies one space in a standard 19-inch rack. The MPS-488HP 
can power up to eight MM-10XP subwoofers.

The MPS-488HP power supply is avail-

able in two models: the MPS-488HPp, which is 

equipped with Phoenix 5-pin male output connec-
tors, and the MPS-488HPe, which is equipped with 
EN3 5-pin female output connectors.

The MPS-488HP front panel includes a power switch and 
LEDs for monitoring each loudspeaker channel.

The MPS-488HP is powered on and off with the AC Power 
switch.

The Voltage and Load Current LEDs are useful for verifying 
whether each channel output has voltage and whether the 
connected loudspeakers are receiving DC power and audio.

The blue Voltage LEDs indicate whether voltage is present 
for each channel output. These LEDs should be lit when the 
MPS-488HP is powered on. The MPS-488HP’s intelligent 
circuit protection shields connected loudspeakers from 
surges and shorts. The blue Voltage LEDs flash on and off 
when a surge or short is encountered. If a channel’s Voltage 
LED flashes on and off, you should power down the 
MPS-488HP and inspect the cabling for that channel.

The green Load Current LEDs indicate whether a loud-
speaker is connected to the channel and receiving power. 
As a channel’s audio signal increases, its LED glows 
brighter. If an LED is not lit, check that the channel’s Voltage 
LED is lit and verify the cable connection to the loudspeaker.
